Additions

Items

Minecraft:Banner patterns

• Two new banner patterns have been added to achieve parity with Template:BE:
  • File:Field Masoned Banner Pattern JE1 BE2.png Minecraft:Field masoned banner pattern
  • File:Bordure Indented Banner Pattern JE1 BE2.png Minecraft:Bordure indented banner pattern

File:Bundle JE2 BE2.png Minecraft:Bundle

• A new item that can hold a mixed stack of up to 64 items.
• Crafted from a Minecraft:string and a piece of Minecraft:leather.

• Can be dyed into 16 colors. Once dyed, the color can not be reset to default.<ref>Template:Bug</ref>

• Items that stack up to 16 take up more space, while items that do not stack take up the entire bundle (except other bundles).
  • Minecraft:Shulker boxes can not be placed in bundles.
  • Bundles can be placed in other bundles; this takes up 4 slots plus the number of slots already used by the inner bundle.
• Has a tooltip that shows the items inside.
  • If a bundle has less than 8 item types inside, the tooltip shows all of them.
  • Otherwise the tooltip shows the top 3 rows of items and the others are hidden below, always showing at least 12 item types.
• When holding a bundle in hand, the player can throw out one group of items onto the ground by pressing Template:Control.
• It is possible to select any of the visible items to pull out of the bundle.
  • Pressing Template:Control takes the selected item, or the first item if nothing is selected.
  • Using the scroll wheel selects a different item.
  • When selecting an item to remove, the bundle icon shows that item poking out of the bundle.

Minecraft:Options

• Added a new accessibility setting that makes players follow the rotation of minecarts they ride.

Minecraft:Shaders

Minecraft:Shader program configurations

• Can now specify preprocessor define directives to be injected into the shader source, which can be referenced in the shader
  • In the vanilla assets, this is used to combine multiple shaders into one program. For example, rendertype_cutout, rendertype_solid, rendertype_cutout_mipped, rendertype_transluscent and rendertype_tripwire now use the terrain.fsh / .vsh shaders. Define directives are used alongside an #ifdef ALPHA_CUTOUT statement in the terrain.fsh program to control if the shader program should discard transparent pixels.
  • These can be specified in a new defines object in the root of the shader json file

• Template:Nbt The root tag
  • Template:Nbt Preprocessor directives that can be used in shader programs.
    • Template:Nbt Preprocessor directives with a value, can be used with #ifdef, #ifndef or directly as a variable in a program.
      • Template:Nbt A preprocessor directive. The key is the name of the directive. It can be anything, but must be in all capitals. Injected as #define <key> <value> at the top of the shader source.
    • Template:Nbt Flag directives, can be used with #ifdef or #ifndef in a program.
      • Template:Nbt The name of a flag. This can be anything, but must be in all capitals. Injected as #define <key> at the top of the shader source.

• The blend field has been removed, as it had no use
• The attributes field has been removed, instead the Position attribute is always bound
• The vertex and fragment shader references in program definitions are now namespaced ids
  • A vertex shader <namespace>:<path> resolves to assets/<namespace>/shaders/<path>.vsh
  • A fragment shader <namespace>:<path> resolves to assets/<namespace>/shaders/<path>.fsh

Uniforms

• The ChunkOffset uniform in terrain shaders has been renamed to ModelOffset
• The Time uniform for post-processing shaders has been replaced with the GameTime uniform from core shaders
• There are 9 new uniforms that are available in the new lightmap shader.
  • AmbientLightFactor, SkyFactor, BlockFactor, UseBrightLightmap, SkyLightColor, NightVisionFactor, DarknessScale, DarkenWorldFactor and BrightnessFactor

Imports

• The #moj_import directive now supports namespaced includes with absolute paths
  • #moj_import <<namespace>:<shader program>> resolves to assets/<namespace>/shaders/include/<shader program>

Post-processing effects

• Post-processing effect configurations have been moved from assets/<namespace>/shaders/post to assets/<namespace>/post_effect
• Vertex and fragment shaders used by post-processing effects have been moved from assets/<namespace>/shaders/program to assets/<namespace>/shaders/post.
• The format of post-processing effect configurations have been updated.
• name has been renamed to program, and is now a namespaced id of a shader program configuration.
  • <namespace>:<path> resolves to assets/<namespace>/shaders/<path>.json.
• intarget and auxtargets have been merged into a single inputs list, as specified by the input format below.
• outtarget has been renamed to output with the same format.
• targets is now a map between target name and target definition, as opposed to a list
  • Inline target names are replaced with an empty object
    • For example, ["swap"] becomes {"swap": {}}
  • Target definitions with a specific size remain the same, with the name field moved into the map key
    • For example, [{"name": "potato", "width": 16, "height": 16}] becomes {"potato": {"width": 16, "height": 16}}

Inputs

• For both render targets and texture inputs, the following fields may be specified:
  • Template:Nbt The prefix to set up both _Sampler and _Size uniforms.
  • Template:Nbt (default: false) If true, the input is sampled with a bilinear filter. For render targets, this replaces the removed use_linear_filter field on the pass definition.

• For inputs from a render target, the following fields may be specified:
  • Template:Nbt The render target id, a namespaced id. Either a custom target id defined in the same file, or minecraft:main to reference the main screen target. This replaces the former id field, which was a free-form string.
  • Template:Nbt (default: false) Set to true to sample from the depth texture, false to sample from the color texture. This replaces the former :depth suffix applied to the target id.

• For inputs from a static texture, the following fields may be specified:
  • Template:Nbt The location to a static texture file that can be sampled by the effect. As the id field did before, this resolves to a texture at assets/<namespace>/textures/effect/<path>.png
  • Template:Nbt Width of the texture in pixels, must be a positive integer.
  • Template:Nbt Height of the texture in pixels, must be a positive integer.

External inputs

• The 'Fabulous' graphics transparency post-processing config no longer specifies the sorted framebuffers as custom targets.

  • translucent, itemEntity, particles, weather, clouds are now minecraft:translucent, minecraft:item_entity, minecraft:particles, minecraft:weather, and minecraft:clouds respectively.
• The entity outline processing shader similarly imports the minecraft:entity_outline target

Core shaders

• Some core shaders now share the same shader programs.
  • The rendertype_clouds shader no longer gets the cloud texture sampler.
  • The rendertype_cutout, rendertype_solid, rendertype_cutout_mipped, rendertype_transluscent and rendertype_tripwire shaders now use the terrain.fsh and terrain.vsh programs.
  • The rendertype_armor_cutout_no_cull, rendertype_breeze_wind, rendertype_energy_swirl, rendertype_entity_cutout_no_cull_z_offset, rendertype_entity_cutout_no_cull, rendertype_entity_cutout, rendertype_entity_no_outline, rendertype_entity_smooth_cutout, rendertype_entity_solid, rendertype_entity_translucent_emissive, rendertype_entity_translucent and rendertype_eyes shaders now use the entity.fsh and entity.vsh programs.
• Most UI elements such as buttons, the inventory, menu backgrounds, the hotbar, etc are now rendered with position_tex_color instead of position_tex

It could be changed independently the world's hardcore mode (set on the world creation screen), which only controlled whether the client is informed hardcore mode is enabled on the server (which in turn decided on the hearts texture and death screen) and forced hard difficulty.
  • The world's hardcore mode is now used for controlling whether the player can respawn, informing the client that the server is hardcore mode and forcing hard difficulty.
